Filed: 1991-11-07
Abstract: PURPOSE:To make an error due to correction disable error inconspicuous. CONSTITUTION:A prediction difference coding code and its error correction code are inputted to an input terminal 50. An error correction circuit 52 corrects an error of a prediction difference coding code. Representative value setting circuits 54-60 and a switch 62 select a correct representative value, an adder 64 adds a prediction value Pi to the representative value to output a decoded value Xi(d). Two 1H delay devices 82, 84, an adder 86 and a coefficient device 88 are used to obtain a signal delayed by 1H from an output of the adder 64 and obtains an average signal of upper and lower lines of the 1H delay signal. A switch 92 selects the signal of the former normally. When an error correction circuit 52 outputs an error signal, a changeover control circuit 90 throws the switch 92 for a prescribed period to the position of a contact (b) and the latter signal is selected.

Title: Process for deodorizing water
Inventor: MATSUMOTO AKIKO
IPC: C02F1/00
Filed: 1988-11-18
Abstract: PURPOSE:To raise the safety in a simple manner at low cost and promote deodorization efficiencies by executing a primary deodorization treatment by the use of ferric chloride and a secondary deodorization treatment by the use of dialdehyde to effect deodorization. CONSTITUTION:Hydrogen sulfide having relatively low odor threshold value is deodorized by using ferric chloride in a primary deodorization treatment stage and complex odor which is still present after said treatment is deodorized by using dialdehydes and the like in a secondary deodorization treatment stage. Reasons for effecting deodorization in two stages are such that reactivity of dialdehyde and the like for hydrogen sulfide in water to be treated is inferior to that of ferric chloride and hence most of hydrogen sulfide is removed by the use of ferric chloride and then other odor is deodorized by dialdehydes. In this way, malodor due to substances other than hydrogen sulfide such as ammonia, amines, derivatives of hydrogen sulfide, etc., is mainly deodorized in the secondary deodorization treatment stage. As a result, malodor due to hydrogen sulfide which has not been removed in the primary treatment stage can also be deodorized in the secondary treatment stage.

Title: Human figure video display system
Inventor: NAGASHIMA YOSHIO
IPC: H04N7/18
Filed: 1993-11-22
Abstract: PURPOSE:To attain the effective use of a transmission line and to secure the sense for each terminal to feel that they are interchanging with each other in the same place. CONSTITUTION:Each of terminals 31-34 sends the video information and the intra-virtual space positional information on its own user to a center device 1. The device 1 separates the video information from the positional information which are received from each terminal and extracts a human figure out of the video information. Meanwhile the device 1 grasps the positional relation among the terminal users in a virtual space based on the received positional information and then changes the number of pixels on a video screen of the human figure image of each terminal user (i.e., magnifies/reduces the human figure image) based on the received positional information. Then the device 1 distributes the processed video information and the positional information on each human figure image to each terminal. Thus each terminal generates a virtual space and displays with mapping each video information in the virtual space based on the positional information received from the device 1.

Abstract: PROBLEM TO BE SOLVED: To provide a cylindrical alkaline battery in which an electrolyte is restrained from being splashed during actuation of an explosion preventive mechanism of a battery due to erroneous use, and a device to be used is hardly damaged. SOLUTION: A resin made sealing body 6 has a return protrusion wall 6b along an outer peripheral rim thereof, a circular thin wall part 6e is formed on a protrusion wall for return this is outer than an opening end of a battery case 1, and a gas exhaust hole 7a of a negative electrode terminal plate 7 is interrupted by a protrusion wall tip end 6f on a tip end more than the circular thin wall part 6e.

Title: Manufacture of semiconductor device
Inventor: TAKEDA YOSHIYA
IPC: H01L21/3065
Filed: 1987-11-19
Abstract: PURPOSE:To perform microetching of a layer without giving no damage to a foundation by using gas for etching containing the first gas having fluorine as a constituent and the second gas having nitrogen as a constituent so as to etch the layer formed on tantalum oxide. CONSTITUTION:Fluorine hydrocarbon system gas such as CF4, CHF3, nitrogen fluoride such as NF3 and XeF are used as the first gas containing fluorine as a constituent, while nitrogen oxide such as N2, N2O and NH3, NF3 are used as the second gas. A means, which generally excites a substance, such as plasma discharge, ultraviolet ray radiation may do as a means for forming the first and the second gas mentioned above into radicals and ions of fluorine and nitrogen. A radical of fluorine reacts on Si to become silicon fluoride and tantalum becomes gas called tantalum fluoride having high vapor pressure so as to advance etching. Here, under existing fluorine, the radical of nitrogen is excluded from advancing to silicon nitride by reacting on Si. However, in the case of tantalum, reaction on tantalum nitride having low vapor pressure on the tantalum surface advances even under existing fluorine to prevent further etching so as to obtain a large etching selection ratio.

IPC: H04L7/033
Filed: 1994-11-28
Abstract: PURPOSE: To synchronize a phase at all times even when any phase deviation is generated between input data and an internal clock. CONSTITUTION: An internal clock signal 101 is delayed for plural stages by a multistage delay element 1, and one of plural clock signals is selected by a selector 2 based on the count value of an up-down (UD) counter 4 and outputted as a clock signal.

IPC: B06B1/02
Filed: 1993-10-28
Abstract: PURPOSE:To provide an ultrasonic cleaning method and device wherein air bubbles formed by the ultrasonic waves of high frequency are broken by the ultrasonic waves of lower frequency. CONSTITUTION:A cleaning tank 1 is provided with low-frequency ultrasonic wave vibrators 2 and 3, low-frequency generators 5, 6 and 7 are connected to the low-frequency ultrasonic wave vibrators 2 and 3 through a switching device 4 and the cleaning tank 1 is also provided with a high-frequency ultrasonic wave vibrator 8 in order to supply a high-frequency output from a high-frequency generator 9 to the high-frequency ultrasonic wave vibrator 8. High-frequency ultrasonic waves are continuously output into the high-frequency ultrasonic wave vibrator 8 from the high-frequency generator 9 to continuously form fine air bubbles in the cleaning tank 1. When such ultrasonic waves are input into the low-frequency ultrasonic wave vibrators 5, 6 and 7 through the output switching device 4, since the air bubbles formed by the high-frequency ultrasonic wave are broken and the ultrasonic wave itself forms air bubbles, the sound pressure occurring at the time of air bubble breakage superimposes the ultrasonic wave already occurring at that time to obtain an extremely high sound pressure, whereby an extremely high cleaning effectiveness can be obtained.

Title: Device and method for mounting solder ball
Inventor: NAKAZATO SHINICHI
IPC: H01L21/60
Filed: 1994-11-28
Abstract: PURPOSE: To provide a device and method by which solder balls can be surely picked up from a solder ball supply section by attracting the solder balls to the suction holes of a head by vacuum suction. CONSTITUTION: In order to evacuate the inside of a head 11, a blower 32 is provided in addition to a vacuum pump 31. The pump 32 can generate a very low air pressure, but cannot suck a large amount of air, whereas the blower 32 cannot generate very low air pressure, but can suck a large amount air. Therefore, when the head 11 is lowered to attract solder balls 3 from a solder ball supply section 1 by vacuum suction, the balls 3 are attracted to the suction holes of the head 11 by utilizing the suction forces of the pump 31 and blower 32. When all suction holes of the head 11 are closed with the balls 3 attracted to the holes by vacuum suction, the head 11 is moved to a board 7 by reducing the suction force of the blower 32 and the balls 3 are mounted on the board 7.
